A compound of the formula (I):
##STR00001##
wherein R1 is hydrogen or lower alkyl;
This invention relates to pyrazole compounds having pharmacological activity, to a process for their production and to a pharmaceutical composition containing the same.
The presence of two cyclooxygenase isoenzymes, cyclooxygenase-I (COX-I) and cyclooxygenase-II (COX-II) is known (Proc. Nat. Acad. Sci. USA 88, 2692–2696 (1991)).
Traditional non steroidal anti-inflammatory compounds (NSAIDs) have inhibiting activities of both COX-I and COX-II (J. Biol. Chem., 268, 6610–6614 (1993), etc). The therapeutic use thereof involves undesired effects on the gastrointestinal tract, such as bleeding, erosions, gastric and intestinal ulcers, etc.
It was reported that selective inhibition of COX-II shows anti-inflammatory and analgesic activities comparable with conventional NSAIDs but with a lower incidence of some gastrointestinal undesired effects (Pro. Nat. Acad. Sci. USA, 91, 3228–3232(1994)). Accordingly, various selective COX-II inhibitors have been prepared. However, it was reported that those “selective COX-II inhibitor” show some side-effects on kidney and/or insufficient efficacy on acute pains.
Further, some compounds such as SC-560, mofezolac, etc, which have certain selective inhibiting activity against COX-I. WO98/57910 shows some compounds having such activity. However, their selectivity of inhibiting COX-I does not seem to be enough to use them as a clinically acceptable and satisfactory analgesic agent due to their gastrointestinal disorders.
WO02/055502 shows some pyridine derivatives having cyclooxygenase inhibiting activity, particularly cyclooxygenase-I inhibiting activity. Further, WO03/040110 shows some triazole derivatives having cyclooxygenase inhibiting activity, particularly cyclooxygenase-I inhibiting activity. And WO99/51580 shows some triazole derivatives having an inhibiting activity of cytokine production.
This invention relates to pyrazole compounds, which have pharmacological activity such as cyclooxygenase (hereinafter described as COX) inhibiting activity, to a process for their production, to a pharmaceutical composition containing the same and to a use thereof.
Accordingly, one object of this invention is to provide the pyrazole compounds, which have a COX inhibiting activity.
Another object of this invention is to provide a process for production of the pyrazole compounds.
A further object of this invention is to provide a pharmaceutical composition containing, as active ingredients, the pyrazole compounds.
Still further object of this invention is to provide a use of the pyrazole compounds for manufacturing a medicament for treating or preventing various diseases.

[A] Analgesic Activity
Effect on Adjuvant Arthritis in Rats:
(i) Test Method
Analgesic activity of a single dose of agents in arthritic rats was studied.
Arthritis was induced by injection of 0.5 mg of Mycobacterium tuberculosis (Difco Laboratories, Detroit, Mich.) in 50 μl of liquid paraffin into the right hind footpad of Lewis rats aged 7 weeks. Arthritic rats were randomized and grouped (n=10) for drug treatment based on pain threshold of left hind paws and body weight on day 22.
Drugs (Test compounds) were administered and the pain threshold was measured 2 hrs after drug administration. The intensity of hyperalgesia was assessed by the method of Randall-Selitto. The mechanical pain threshold of the left hind paw (uninjected hind paw) was determined by compressing the ankle joint with a balance pressure apparatus (Ugo Basile Co. Ltd., Varese, Italy). The threshold pressure of rats squeaking or struggling was expressed in grams. The threshold pressure of rats treated with drugs was compared with that of non-treated rats. A dose showing the ratio of 1.5 is considered to be the effective dose.

(i) Test Metho:
Whole Blood Assay for COX-I
Fresh blood was collected by syringe without anticoagulants from volunteers with consent. The subjects had no apparent inflammatory conditions and had not taken any medication for at least 7 days prior to blood collection.
500 μl Aliquots of human whole blood were immediately incubated with 2 μl of either dimethyl sulfoxide vehicle or a test compound at final concentrations for 1 hr at 37° C. to allow the blood to clot. Appropriate treatments (no incubation) were used as blanks. At the end of the incubation, 5 μl of 250 mM Indomethacin was added to stop the reaction. The blood was centrifuged at 6000×g for 5 min at 4° C. to obtain serum. A 100 μl aliquot of serum was mixed with 400 μl methanol for protein precipitation. The supernatant was obtained by centrifuging at 6000×g for 5 min at 4° C. and was assayed for TXB2 using an enzyme immunoassay kit according to the manufacturer's procedure. For a test compound, the results were expressed as percent inhibition of thromboxane B2(TXB2) production relative to control incubations containing dimethyl sulfoxide vehicle.
The data were analyzed by that a test compound at the indicated concentrations was changed log value and was applied simple linear regression. IC50 value was calculated by least squares method.
Whole Blood Assay for COX-II
Fresh blood was collected in heparinized tubes by syringe from volunteers with consent. The subjects had no apparent inflammatory conditions and had not taken any medication for at least 7 days prior to blood collection.
500 μl aliquots of human whole blood were incubated with either 2 μl dimethyl sulfoxide vehicle or 2 μl of a test compound at final concentrations for 15 min at 37° C. This was followed by incubation of the blood with 10 μl of 5 mg/ml lipopolysaccharide for 24 hrs at 37° C. for induction of COX-II. Appropriate PBS treatments (no LPS) were used as blanks. At the end of the incubation, the blood was centrifuged at 6000×g for 5 min at 4° C. to obtain plasma. A 100 μl aliquot of plasma was mixed with 400 μl methanol for protein precipitation. The supernatant was obtained by centrifuging at 6000×g for 5 min at 4° C. and was assayed for prostaglandin E2 (PGE2) using a radioimmunoassay kit after conversion of PGE2 to its methyl oximate derivative according to the manufacturer's procedure.
For a test compound, the results were expressed as percent inhibition of PGE2 production relative to control incubations containing dimethyl sulfoxide vehicle. The data were analyzed by that a test compound at the indicated concentrations was changed log value and was applied simple linear regression. IC50 value was calculated by least squares method.

The residue was purified by preparative thin layer silica gel chromatography developed by AcOEt/n-hexane=70%. The separated silica gel was extracted with 10% MeOH/CHCl3 and the solvent was evaporated in vacuo. The residue was recrystallized from AcOEt-IPE to give N-(2-{4-[3-isopropyl-1-(6-methoxy-3-pyridinyl)-1H-pyrazol-5-yl]phenoxy}ethyl)methanesulfonamide (68.6 mg) as white powder.

The mixture was stirred at ambient temperature for 1 hour. Additional methanesulfonyl chloride (6.9 μl ) and Et3N (41.6 μl) were added and the reaction mixture was stirred at ambient temperature for 30 minutes. The mixture was concentrated in vacuo, and the residue was partitioned between AcOEt and 1M HCl. The aqueous layer was reextracted with AcOEt. The combined organic layers were washed with saturated aqueous sodiumbicarbonate solution and saturated aqueous sodium chloride solution, dried over magnesium sulfate, and concentrated in vacuo. The residue was purified by preparative thin layer silica gel chromatography developed by AcOEt/n-hexane=70%. The seaparated silica gel was extracted with 10% MeOH/CDCl3 and the solvent was evaporated in vacuo. The residue was crystallized from AcOEt-IPE to give N-(2-{4-[3-isopropenyl-1-(6-methoxy-3-pyridinyl)-1H-pyrazol-5-yl]phenoxy}ethyl)methane-sulfonamide (48.0 mg) as white powder.
